小珂最近有一个麻烦,就是要统计一下指定区域中有几个方格被染黑了.表格的布局及表格各个位置的坐标如下所示.有三种操作命令,BLACK x,y,l 表示把以坐标（x,y）为左上角顶点，（x+l-1,y+l-1）为右下角顶点的矩形染黑。WHITE x,y,l 表示吧指定区域染白。TEST x,y,l 表示计算指定区域的黑块的个数。说明：如果 x,y,x+l-1 ,y+l-1超出图表的范围，就只计算图表内部的。输入第一行有一个整数n(0<n<100)，表示有n条命令，随后的n行有n个指令。输出遇到TEST命令，把结果输出并换行。样例输入5 BLACK 1 1 2 BLACK 2 2 2 T...

One measure of ``unsortedness'' in a sequence is the number of pairs of entries that are out of order with respect to each other. For instance, in the letter sequence ``DAABEC'', this measure is 5, since D is greater than four letters to its right and E is greater than one letter to its right. ...
